Abstract

In this study, we evaluated the effects of isometric exercise, performed at 75% of the maximal voluntary contraction for 3 minutes, on left ventricular mechanical function in 20 patients with angiographic evidence of critical coronary artery stenosis and in 10 normal subjects. Of the 20 patients with critical coronary stenosis, 16 developed wall motion abnormalities during the test (sensitivity = 80%); in no case did we observe myocardial asynergies in the control group (specificity = 100%). None of the 30 patients manifested electrocardiographic or symptomatological signs of ischemia during the test. Our data demonstrate that isometric exercise is a stress test that can achieve useful and reproducible results in the noninvasive detection of coronary artery disease.
